Summary: Predicted to enable SNAP receptor activity; SNARE binding activity; and arachidonate binding activity. Involved in exocytic insertion of neurotransmitter receptor to postsynaptic membrane; modulation of chemical synaptic transmission; and vesicle-mediated transport in synapse. Acts upstream of or within exocytosis and long-term synaptic potentiation. Located in several cellular components, including cytoplasmic vesicle; photoreceptor inner segment; and photoreceptor outer segment. Part of SNARE complex. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and postsynapse. Is expressed in several structures, including alimentary system; central nervous system; eye; genitourinary system; and respiratory system. Human ortholog(s) of this gene implicated in congenital diarrhea. Orthologous to human STX3 (syntaxin 3). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
